Application filed March 6. 1915.

To all whom '1' t nirz conw'rn Be it known that I, l lilniciz \Vnrrunn, a citizen of the United States, residing at (llendive. in the county of Dawson and State of Montana, have invented certain new and useful Improvements in Means for Extracting heels of lower Drivcn Vehicles iroin lloles, ot which the following is a s 'iec'ification, reference being had to the accoinpaiiyingz drawings.

This invention relates to certain improvements in means for extracting wheels of power driven vehicles from holes, and it is an object of Iiiy invention to provide novel and improved means of this general char acter wherein the drive wheels of the vehicle may be en'iployed as the operative power.

Finthermorc, it is an obje'ct of my invention to provide noveland improved means oi this general character whereby the antiskidding or mud chains now in geueral use may be employed with convenience and facility.

It is also an object of my invention to provide novel and improved means of this general character including a flexible member adapted to be? olierati'vely engaged with a .drive \vhcel' and with a stationary anchoring member whereby said flexible member will be automatically disengaged from the stationary anchoring member as the wheel passes thereover.

lhe invention consists in the details of arrangement ofthesevcral parts of my improved device whereby certain important advantages are attained and the. device is rendered simpler, less expensive and other wise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be'carefully defined in the appended claims. In order that my invention maybe the better understood,'-I wil1 now proceedto d escribethe same with reference to the accornpanying drawings,- wherein Figure 1] is an elevational VlQW illustratingan embodiment of my invention in operative assemblage; F ig. 2 is a view in perspective of the means as herein embodied,

and disengaged from a driving wheel; Fig

3 is an elevational View illustrating; a further embodiment of my invention, as relates to the wheel engaging means, in applied position; and Fig. dis a view in perspective,

mud chain of conventional construction such as the wellknown \Veed chain. although I do not wislrto be understood as limitin my self to anyparticular style of chain. 1 also wish it to be understood that in lieu of chains. other flexible men'ibers may be employed, such as cables as will be, it is thought. clearly obvious to those skilled in the art towhich my invention appertains.

1 denotes a yoke adaptcd to bridge or straddle the rim or telly of the wheel \V and the free extremities of the yoke terminate in the hook members 2 so that the same may be readily engaged with the parallel members 3 ofl' the chain C, in a manner which is believed 'to be self-evident, and the connecting, portion 4 of the yoke is provided with the annularly disposed flanges 5 adapted to afford an increased bearing surface for contact \viththe inner face of the. rim or felly and an adjacent spoke of the wheel structure W. Y

6 denotes an anchoring member provided with the opening 7 through which are adapted to be disposed the securing stakes 8, whereby it'will be readily perceived that the anchoringplate 6 will be maintained upon the ground in a substantially stationary manner. One extremity of the plate 6 is provided, with the upstanding and rearwardly disposedhook member 9 with which is loosely engaged the yoke 10, the free extremity whereof being also provided with the hooks 11 adapted for convenient engagement withthe parallel members 3 and the stems 12 of the yoke lOat a point intermediate their lengths are tied or connected by the transverse member H in order to'increase the cflieiency of the yoke. v

It is to be particularly noted that as the wheel \V passes beyond the ai'ichoring plate 6 the yoke 10 will be automatically disengaged from the hook member 9 whereby the possi-- bility of injuryto the Wheel structure is entirely eliminated.

In the. form of invention-illustrated in Figs. 3 and 4-, Iemploy a wheel engaging member including a yoke adapted to straddlethe felly F of a Wheel, said yoke being substantially U-shape in form, and pivotally engaged intermediate their lengths with the stems of said yoke '15 are the levers 16 terminating at their op'posite extremiare the extremi ties'of the flexible member 18 ties in the hook member-17 and vvith adj a;-

I cent hook members l7 are adapted to be secured the parallel members 3*" of anantiskidding chain or the like. Deta'chably engaged With the opposite hook members 17 which is adap ted to straddle the tread portion of the wheel'VV' whereby it will'be perceived that upon rotation .of the Wheel W, the resultant strain imposed upon'thearm 16 will serve to. effectively securethe yoke 15 in operative position. This form of securing means is particularlydesired When the spokes S of the wheel structure are of Wire or 'the'like. I I Y From the foregoing description, it is thought that a means for extracting wheels of powerdriven vehicles from holes constructed in accordance vvith my invention is of an extremely simple and comparatively.

inexpensive nature and is particularly Well adapted for use by reason of the convenience and facility With which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification withoutmaterial departure from the principlesand spirit thereof and 'tremity of the plate, aqyoke detachably em gageable with. the :hook member, a .flexible member engageable With the extremities of the yoke, and wheel engaging means engageablewith the flexible member. v

2. .Means for the purposews'et forth comprising ama-nchoring plate providedwith securing means, a flexiblemember'engageable with the plate, a yoke adapted to straddle. f

the rim portion of a Wheel structure, arms pivotally engaged Wltlltl'l6 y0k6 and posi-v tioned at opposite sides of the rim portion,

the opposite extremitiesof 'said armsbeing provided With hooks, said flexible member being engageable vvith 'thealhooks at adjacent extremities of the arm'sfand asecond flexible member engageablewwith the opposite hooks of the arms and adapted to straddle the tread portion of. the .Wheel structure.

- In testimony whereof-I hereunto afiix my I signature in the presence 'ofwtwo Witnesses.
